The world has dramatically changed since 9/11. The insurgent and terrorist threats in countries like Iraq, Afghanistan and India have changed from small arms fire to the use of Improvised Explosive Devices (IEDs) and Explosively Formed Penetrators (EFPs). These devices are injuring and claiming the lives of numerous American and Allied Force troops.

Defence departments globally have incorporated aggressive survivability strategies to combat these threats. The three key requirements relating to military vehicles include an increase in survivability levels, weight reduction and an increase in maneuverability. In summary, defence officials constantly repeat "We want light but strong!". The inherent paradox of these objectives bring innovative products such as Cymat's SmartMetal™ to the forefront of today's designs.

Cymat's products are being sought after for present and future generation vehicles to ensure that an effective solution is produced for increasing survivability levels.

Cymat-SmartMetal-Coyote"SmartMetal™" is effective in absorbing large amounts of energy in an efficient lightweight recyclable package. It can be engineered into a wide range of applications to provide effective blast ballistic attenuation from an assortment of present and future threats.

Based on independent testing completed in the United States, Cymat’s SmartMetal™ plays a key role in increasing troop survivability in today's conflicts.

SmartMetal™'s cellular structure is the key to its large energy absorption capabilities. As a blast front hits SmartMetal™, t

 

he bubbles collapse, absorbing energy and attenuates the transfer of this destructive force to targeted vehicles or building structures and its occupants.

This Canadian owned and developed technology is gaining global recognition as an integral solution against the war on terror.

 

SmartMetal™ Features:

Cymat's SmartMetal is a unique product that can provide the following key features:

  • Energy absorption
  • Multi-hit capabilities
  • Isotropic
  • Lightweight
  • Recyclable
  • Improves structural integrity
  • Sound attenuating
  • Time and temperature stable
  • Cut to size using various means
  • Machinable
  • Can be laminated and coated into a composite kit

Energy Absorption

The key to SmartMetal's energy absorbing properties is its cellular structure. When a blast wave impacts a panel of SmartMetal the cells/bubbles begin to fracture and compress. This act of compression absorbs energy and attenuates the impulse from transferring to a vehicle body or building structure. The stress-strain graph presented below outlines the typical compressive strength of a specific density of Cymat SmartMetal. Because of SmartMetal's isotropic features and the production process’ ability to adjust to a wide range of thicknesses and densities multi-hit capabilities can be designed into the product to increase the survivability level of the complete energy absorbing system.

SmartMetal™ is manufactured into large dimensional panels for both interior and exterior blast attenuating systems as well as near-net shaped castings for more complex geometric volumes found in internal vehicle structures.
